The Postman (1997)

An adventure directed by and starring Kevin Costner, with a cameo by Tom Petty.
In a post-apocalyptic America, a vagabond is captured by an army and forced into hard labor. He escapes, finds a mail truck and convinces everyone in a small town that he is "The Postman", a representative of the reformed government. He pretends to induct a young man who starts a real postal service. The army that the vagabond escaped from hates the old America and tries to hunt and kill the postman and destroy everything that he supposedly stands for.
This film was long (almost 3 hours), but good. The plot was epic and the characters dynamic. I think I liked it because it was just a "big" movie. I'm rating it good.
